Answer:
a = 7.5 [m/s²]
Explanation:
To solve this type of problem we must remember Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
∑F = sum of forces [N]
m = mass = 0.1 [kg]
a = acceleration [m/s²]
Now replacing:
[tex]0.9-0.15=0.1*a\\a=7.5 [m/s^{2} ][/tex]
